Threaded Collet
This procedure describes how to install threaded collets.
1. Ensure that the grips are in the release condition and that hydraulic pressure
is turned off.
2. Clean the surface of the preload platen which will contact the surface of the
threaded insert with acetone or any other volatile solvent that does not leave
a residue.
3. Apply a thin layer of Molykote G·n paste (part of the grip service kit) to this
surface of the preload platen.
4. Insert the retainer screw into the preload platen.
5. Insert the preload platen into the grip, aligning the retaining screw with the
threaded hole in the grip piston. Secure the preload platen by screwing the
retaining screw into the grip piston.
